Berkshire Volume Nears 20 Million

In the least, active managers the world over can't be too happy on Wednesday: it may have just gotten a little bit harder for active managers to beat the indexes, now going up against Warren Buffett as part of the S&P return mix.

However, it has become a lot easier for investors to gain access to the Oracle of Omaha through the Berkshire Hathaway B Shares, and at least through the first week of trading, and especially with Wednesday's 11 million shares by mid-day, it wasn't just S&P that decided to bulk up on Buffett.

Of course, it's not just a little of Warren Buffett headed into the S&P 500. Berkshire's legendary portfolio includes many of the global corporate elite also: a 12.8% stake in American Express(AXP); 9.4% in Kraft; close to 7% in Wells Fargo(WFC); a little under 1% of Wal-Mart(WMT); and close to 9% of Coca Cola(KO).
